to cause this you must grid these rail's : EasternTremor, westenTremor, NorthernTremor, and Sothern Tremor.(they dont have to be in that order.) (FROM were you start, im gonna call that the front!)the front of building go inside if you go strait that is the western rail.. on the left side of that that is the eastern rail.(its on the outside). and on the right side of the W.rail there is more than one rail,(on the out side) the straitest one closest to the roude is the northern.rail to the left of the northern rail is the southern rail grid them all. then there will be an earthquake! then go to the car wash and get on the roof of it, the brokn brige has new gaps so get on it. (you will see a peace of the brige, Ride up it!) or you can climb up the building and jump on it. you will see a peace of wood like a ramp. ramp up it thats a gap. and at the begining of it you will see a car, get on top of it and walk to the back of it, it will fall off and hit a sign. thats a gap.
When your on Berlin level (Or the place where you set off the cannons, and be Benjamin Franklin as a character can't remember the name sorry) you will obviously notice 2 skating ranks below 2 buildings. Ride up and crash through the window on your left. You should see a fat kid with sunglasses and a stick. Press circle near him and he'll "try" to harness a "lightsabor". Crash through the window on the right and you'll see a man standing with a lamb, goat or other animal.
